These include a range of formulations for thermionic and field effect surface emission, secondary emission from surfaces and from within volumes, and magnetized plasma emission the last of these being a specialized plasma emission module designed for the efficient analysis of magnetron sputter coating systems.
The hyperopic shift in refraction observed in ketamineâxylazine-anesthetized mice theoretically may be caused by either reduction in the axial length of the eye or changes in the refractive indices of the ocular media.
Natural Hyperopic Shift. Many people become more hyperopic in the fifth and sixth decade of life. The natural hyperopic shift may not explain all of the phenomena of hyperopia after RK, however the natural changes of the eye it may be responsible for some. RK Corneal Weakening
